Research Design
These are the three main categories of applied research.
Descriptive, Experimental, Quasi-experimental
They authored the famous chapter "Applied Research Design"
Leonard Bickman and Debra J. Rog
The two broad categories of sources of data
Primary and secondary
True or false: Data are useful, if not accurate valid and reliable
False
These are used to obtain information from a large number of respondents.
Mail and telephone surveys.
The purpose of descriptive research is not...
to provide cause and effect relationships
They should anticipate the amount of data that will be needed to conduct a study.
Research planner
Data collected for health and health related research
Bio-behavioral
Even if data can be easily collected, it needs to fit
The necessary parameters of the research design
This data can be collected very rapidly, has no data entry costs and are almost immediately available to the researcher.
Web-based/Online surveys
Key feature in experimental research designs
Randomized assignment
This is one way to increase statistical power.
Increasing the sample size
The form of data is from asking participants to provide information on self-interest
Self-reporting
It is important to remember all just about all measures contain some degree of
Error
The type of instrument used when instructions are heard, not just read
Audio-computer assisted self-interview
Quasi-experimental designs are used when
Random assignment is not feasible or desired
This is proceeded be a set of sequenced inquires designed to collect information about attitudes, opinions, memories of events, characteristics and circumstances.
A structured interview guide
Data where events, actions or circumstances are the major form
Observation
Random error can best be controlled through
Using uniform procedures for data collection
Begins with n explanation of purpose for the interview
Structured interview guide
Increasingly used technique for helping to correct for selection bias between treatment and comparison groups
Propensity score
This has a clear impact on defining the population of a study
Site selection
Agencies with increased emphasis researching performance monitoring and management information systems receive this type of funding
Government
Measuring what we intend to measure
Construct validity
Forms needed when there are multiple data collectors
Observational recording forms
